SHS 90x90x9.5 Açotubo · Weight & Dimensions

Açotubo, cold-formed sections · Square Hollow Section

Square Hollow Sections (SHS) are tubular profiles with equal sides, ideal for columns and compression members due to their uniform buckling resistance in all directions.

Also known as: PTR 90x90 (México) · Caño estructural 90x90 (Argentina)

The SHS 90x90x9.5 steel profile weighs 22.2 kg/m (14.91 lb/ft), has a depth of 90 mm (3.54 in), flange width 90 mm (3.54 in). Cross-sectional area: 2,826.586 mm². Moment of inertia Ix = 291.775 cm⁴, Iy = 291.775 cm⁴.
